Moving Average Envelopes
Moving Average Envelopes is a price band channel overlay that is offset from the moving average of price. [Discuss]
// usage IEnumerable<MaEnvelopeResult> results = quotes.GetMaEnvelopes(lookbackPeriods, percentOffset, movingAverageType);
int - Number of periods (
N) in the moving average. Must be greater than 1.
double - Percent offset for envelope width. Example: 3.5% would be entered as 3.5 (not 0.035). Must be greater than 0. Typical values range from 2 to 10. Default is 2.5.
MaType - Type of moving average (e.g. SMA, EMA, HMA). See MaType options below. Default is
Historical quotes requirements
See links in the supported MaType options section below for details on the inherited requirements for
quotes is a collection of generic
TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.
These are the supported moving average types:
MaType.ALMA - Arnaud Legoux Moving Average
MaType.DEMA - Double Exponential Moving Average
MaType.EPMA - Endpoint Moving Average
MaType.EMA - Exponential Moving Average
MaType.HMA - Hull Moving Average
MaType.SMA - Simple Moving Average (default)
MaType.SMMA - Smoothed Moving Average
MaType.TEMA - Triple Exponential Moving Average
MaType.WMA - Weighted Moving Average
Warning: For ALMA, default values are used for
- This method returns a time series of all available indicator values for the
- It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first periods will have
nullvalues since there’s not enough data to calculate; the quantity will vary based on the
Convergence warning: Some moving average variants have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods. See links in the supported MaType options section above for more information.
DateTime - Date from evaluated
double - Moving average
double - Upper envelope band
double - Lower envelope band
The moving average
Centerline is based on the
movingAverageType type specified.
